Northeastern Colorado, including Denver and the northern Front Range, is under a blizzard warning starting at noon Wednesday and travel, on the ground and in the air, will likely be impacted by the wintry weather.

Airlines serving Denver International Airport, and other airports in the Midwestern United States, are offering travel waivers for customers who could be slammed by the strong winter storm. Travelers flying on Wednesday and Thursday can change flights at no charge on some routes with multiple airlines.

Frontier Airlines announced in a travel advisory that customers scheduled to travel between Wednesday and Thursday, who purchased tickets before April 9, will be able to make one itinerary change with tradition rules and restrictions waived. That’s as long as travel is completed no later than April 26. Customers whose flights are cancelled can request a refund, the airline announced.

The Frontier advisory applies to multiple cities including Denver and Colorado Springs.

United Airlines on Tuesday announced a waiver policy as well for the “Great Plains and Colorado due to winter weather.”

Denver International Airport officials said they expect snow Wednesday afternoon, crews are prepared and the airport will be open. DIA urged travelers to check with their airlines on flight status.

On Tuesday in Denver the high temperature hit 78 degrees, three-degrees shy of tying a record high for April 9 in the city, according to the National Weather Service.

Wednesday’s weather in Denver and northeastern Colorado will be cold, windy and snowy, according to weather service forecasters.

Other cities in the “Blizzard Warning” include Akron, Castle Rock, Fort Collins, Fort Lupton, Fort Morgan, Greeley, Julesburg, Limon and Sterling. The entire Denver metro area, including DIA, is also under the warning.

The northern, central and southwest mountains on Wednesday are under a winter storm warning and winter weather advisory. Snow is expected, up to 14 inches in some areas, including Summit County, Indian Peaks, Rabbit Ears Pass, North Park and Rocky Mountain National Park. Winds in the mountains will gust to 40 mph, the weather service reports.

Winds in northeastern Colorado on Wednesday, in far-flung blizzard warning areas, are expected to gust up to 60 mph. The weather service describes Wednesday’s weather as “drastic.” Snowfall in northeastern Colorado will be between 4 to 8 inches. The winter storm is likely to cause tree damage, and high winds are likely to topple some fences.

“Areas of heavy snowfall across the Front Range to the far eastern plains and strong winds will result in poor visibility and difficult driving conditions,” the weather service said. “Temperatures plummeting will result
in icy roads.”

In Denver, evening commuters should expect a hampered drive home with “hazardous conditions.” Whiteout conditions “making travel extremely dangerous” will be possible. “If you must travel, have a winter survival kit with you,” the weather service said. “If you get stranded, stay with your vehicle.”

In Denver on Wednesday rain showers are expected at about 2 p.m., changing to snow sometime before 5 p.m., the weather service said. A high temperature, of about 51 degrees, will top out at about 9 a.m. and temps will drop the rest of the day, falling into the mid-30s. Snow will continue into the night, being heavy at times.

Snow could linger into Thursday morning in Denver, with a 20-percent chance, the weather service said. Skies will be cloudy with a high temperature near 42 degrees.

Last month, a “bomb cyclone” hit the Denver area and Eastern Plains, leaving hundreds of drivers stranded on windblown roadways and thousands of travelers stranded and delayed at DIA. Colorado State Patrol Cpl. Daniel Groves, 52, was killed in last month’s blizzard when struck by a driver on Interstate 76.
